PURPOSE:To process a work of a material or shape which can be processed only by the slight quantity of laser power by means of not a pulse laser but a continuously oscillating laser by inclining the work and controlling the incident laser power. CONSTITUTION:Laser beam processing is controlled by irradiating the laser beam 11 at certain angle theta on a work surface 12, increasing the reflectivity of the laser beam 13 and making incident only the laser power necessary for the actual processing as the laser beam 14 on the work surface. The work is inclined by certain angle theta by changing the position or posture of the work so as not to melt the work at a part 203 by excessively large heat input and the laser beam processing is executed by controlling the laser power, i.e., the heat input to the work so as to suppress the same in the case of, for example, cutting out the work 202 from a flat plate 201. |
